I am planning to take few more lessons and was talking to an instructor today at the range. He tells me that if the grip and stance are correct, 80% of the work is done. What happens during the swing is only 20% remaining and not very critical. Thus if your grip, stance and ball position are perfect, you can hit the ball well even if your swing is not perfect. I find this is too easy, too good to be true and thus hard to believe because I am still struggling with hitting the ball well after so many practice rounds and rounds on the course although I am not sure if my grip and stance are perfect.
Any thoughts ?
